As a bridge or medium- and small-scale open-covered tunnel, an arch-shaped arch structure curved upwards convexly is used. Republic of Korea Patent No. 10-1157638 discloses that a plurality of concrete blocks having a rectangular cross section are arranged in a row in an arch direction, and the plurality of concrete blocks are integrated using a fiber mesh connecting material to form an assembly, and then transported to the site. A technique for constructing arch structures such as bridges, tunnels, and arched roofs is introduced by lifting them with a crane and installing them to form an arch. For convenience, an assembly made by integrating a plurality of concrete blocks is described as a "block assembly", and an arch-shaped structure made by lifting the block assembly is described as an "arch structure".

In this prior art, since the connecting material is made of a fiber mesh, it has only a purpose and function for simply connecting a plurality of concrete blocks, and there is no function of reinforcing the rigidity of the block assembly in the arch direction. As an alternative to this problem, a technology of connecting concrete blocks with reinforcing bars and installing steel wires in the arch direction has been proposed. In the case of this prior art using reinforcing bars and steel wires, although it is effective for reinforcing the rigidity of the block assembly, when the block assembly is lifted to create an arch structure in the shape of an arch, tension is generated in the reinforcing bars or steel wire, which may cause local damage to the concrete block this is very high In addition, when an arch structure is made by lifting the block assembly, the concrete blocks located at both ends of the arch structure in the arch direction are lifted upward due to tension generation.

In this case, when the arch structure is mounted on the base located on both sides of the arch direction, in order to maintain the arch shape of the arch structure as designed and ensure that both ends are accurately positioned on the base, both ends of the arch structure are placed at the center of the arch. In other words, it is necessary to perform a wire pulling operation in which the wire is pulled in the central direction by tying the wire to both ends of the arch structure, which causes inconvenience in construction and consequently increases the construction cost and air time. do. In addition, in the process of making both ends of the arch structure positioned on the base, the arch structure may be overturned, or both ends may not be accurately positioned on the base.

In constructing a structure using an arch structure, when arranging and integrating a plurality of arch structures side by side in the transverse direction (direction orthogonal to the arch direction), it is convenient and efficient to And it is necessary to firmly integrate, and the prior art does not yet provide a sufficient solution for this.

Republic of Korea Patent No. 10-1157638 (published on June 19, 2012).

The second rotating body is provided with a rotation coupling part, so that the rotation coupling part is rotatably coupled to rotate the first rotation body and the second rotation body to have a configuration that can be bent at the rotation coupling part; There is provided a concrete block assembly for building an arch structure, characterized in that when the upper body is lifted upwards, it is bent in an arcuate shape to form an arch structure.

In addition, in the present invention, in order to achieve the above object, a plurality of concrete blocks are arranged in a row in the arch direction, and the block assembly made by connecting is lifted and bent to form an arch-shaped arch structure, and then the arch structure is spaced apart in the arch direction. Provided are an arch structure that is mounted between the arranged foundations, and is configured by mounting a plurality of arch structures in the transverse direction, and an arch structure characterized by using the block assembly of the present invention as described above, and a method of constructing the same.

In the block assembly according to the present invention, the adjacent concrete blocks are rotated and bent in the vertical direction using the rotation coupling part of the buried hinge connector as the hinge point, thereby forming an arch-shaped arch structure conforming to the design. Since a separate tension does not act on the lower body of the concrete block, a phenomenon that causes local damage to the concrete block caused by tension in the reinforcing bar or steel wire in the process of making the arch shape, which was a problem in the prior art, and the amount of the arch structure It is possible to prevent the problem that the end is indented.

In addition, in the present invention, it is possible to increase the rigidity of the concrete block through the concrete block embedding arrangement of the buried hinge connector.

Therefore, the buried hinge connector 2 is the first rotating body 21 and the second rotating body 22 as shown in Fig. 3 (a) form a straight line, or a portion connected to each other as a hinge point to the first By rotating the rotating body 21 and the second rotating body 22, it can be bent as shown in Fig. 3 (b) or Fig. 3 (c). The first rotating body 21 and the second rotating body 22 are provided with rotation coupling parts 213 and 223 so that the rotation coupling parts 213 and 223 are rotatably coupled. The rotation coupling parts 213 and 223 are each made of a rod member extending in the transverse direction, and the rotation coupling parts 213 and 223 on both sides are arranged to form a straight line in the transverse direction, and then are rotatably coupled by a hinge pin. . As described above, the first rotating body 21 and the second rotating body 22 are integrally rotatably assembled to form the embedded hinge connector 2 .

That is, it is divided into upper embedding parts 212 and 222 embedded in the upper body 12 positioned above the lower body 11 . That is, each concrete block 1 constituting the block assembly 100 is divided into a lower body 11 and an upper body 12 corresponding to a portion existing above it, and the lower portion of the embedded hinge connector 2 . The buried portions 211 and 221 are embedded in the lower body 11 , and the upper buried portions 212 and 222 of the embedded hinge connector 2 are embedded in the upper body 12 . When viewed in the transverse direction, the lower body 11 of the concrete block 1 has an inverted trapezoidal side surface in which the arch direction length of the lower surface is shorter than the arch direction length of the upper surface of the lower body 11 as shown in FIG. 5 .

The bar member is provided on the lower surface of the upper buried part (212, 222) to form the lower buried part (211, 221). When the upper buried parts 212 and 222 and the lower buried parts 211 and 221 are formed of a rod member, the adjacent buried hinges are connected while the rod members are fitted with each other in the adjacent buried hinge connector 2 . The connector 2 may be connected to each other to form an integral body. 6 (a) and (b) are schematic exploded perspective views showing that a plurality of adjacent buried hinge connectors 2 are connected to each other, respectively, an assembled perspective view is shown. It is possible to make the integration between the concrete blocks 1 in the block assembly 100 more robust through the integral connection configuration between the buried hinge connectors 2 . However, the members forming the lower buried portions 211 and 221 and the upper buried portions 212 and 222 are not limited to the rod member, and may be formed of various types of members, such as a plate-shaped member. Whether the members constituting the lower buried parts 211 and 221 and the upper buried parts 212 and 222 are made of a rod member or other various types of members, the lower buried parts 211 and 221 and the upper buried part ( When the members 212 and 222) are made of a member extending in the arch direction or have a portion extending long in the arch direction, the member constituting the same is embedded in the concrete block, thereby exhibiting the effect of reinforcing the concrete block itself.

In the buried hinge connector 2 , the upper buried parts 212 and 222 and the lower buried parts 211 and 221 are integrally formed. If necessary, the upper buried parts 212 and 222 and the lower buried parts 211 and 221 are formed. ) may have a configuration that forms an integral body by being separated and then assembled with each other. 7 is a schematic exploded perspective view showing a configuration in which the upper buried parts 212 and 222 and the lower buried parts 211 and 221 are separated from the buried hinge connector 2 .

In order to manufacture the block assembly 100 in a factory, a plurality of buried hinge connectors 2 are arranged in a row in the arcuate direction, and at the same time, the plurality of buried hinge connectors 2 are connected to each other and buried hinge connectors for axial force or distortion ( In order to improve the resistance of 2), the transverse reinforcement member 8 may be further provided if necessary. 8 is a schematic exploded perspective view showing that the transverse reinforcing member 8 is coupled in a state in which the three buried hinge connectors 2 are arranged in a row in the arcuate direction, and in FIG. 9 , the lateral side reinforcing member 8 is shown in FIG. A schematic assembling perspective view of the state in which the coupling of the reinforcing member 8 is completed is shown.

As illustrated in the drawing, the transverse reinforcing member 8 is composed of a bar member extending in the arcuate direction, and a pair is installed on both lateral sides (both lateral sides) of the buried hinge connector 2, one end of the transverse reinforcing member 8 is rotatably coupled to the rotation coupling parts 213 and 223 of one buried hinge connector 2 and the other end is rotatably coupled to the rotation coupling parts 213 and 223 of the embedded hinge connector 2 adjacent thereto. . 8 and 9 show that the three buried hinge connectors are integrally coupled. For convenience, the three buried hinge connectors shown in FIGS. 8 and 9 are sequentially replaced with the first buried hinge connector 2-1, the second The two buried hinge connectors (2-2) and the third buried hinge connectors (2-3) are called. And the transverse reinforcing member installed between the first buried hinge connector 2-1 and the second buried hinge connector 2-2 is called the first transverse reinforcing member 8-1 for convenience, and the second buried hinge connector The lateral reinforcing member installed between (2-2) and the third buried hinge connector (2-3) is called a second transverse reinforcing member (8-2) for convenience. As illustrated in the drawing, one end of the bar member of the first transverse reinforcing member 8-1 is rotatably coupled to the rotation coupling portions 213 and 223 of the first buried hinge connector 2-1, and the other end is It is rotatably coupled to the rotation coupling portions 213 and 223 of the second buried hinge connector 2-2. And one end of the bar member of the second transverse reinforcing member 8-2 is rotatably coupled to the rotation coupling portions 213 and 223 of the second buried hinge connector 2-2, and the other end is the third buried hinge connector 2-2. It is rotatably coupled to the rotation coupling portions 213 and 223 of (2-3). As such, the transverse reinforcing member 8 consists of a pair of bar members, each bar member being disposed on the transverse side of the buried hinge connector 2 between the adjacent buried hinge connectors 2, Both ends are rotatably coupled to the rotation coupling portions 213 and 223, respectively. Such lateral reinforcing member 8 connects adjacent buried hinge connectors 2 to each other without any obstruction when the buried hinge connector 2 is bent by rotation, and the axial force exerted by the buried hinge connector It further enhances resistance to twisting, etc., and exerts a reinforcing function. In addition, the transverse reinforcing member 8 is embedded in the upper body 12 of the concrete block 1 to exhibit a function of further reinforcing the concrete of the upper body 12 .

10 to 13 are schematic views sequentially showing a process of manufacturing a block assembly by embedding and integrating an embedded hinge connector in a concrete block, respectively. For convenience, only four concrete blocks are shown in FIGS. 10 to 13 . As shown in Fig. 10, first, the formwork 19 for the production of the concrete block 1 is arranged in a row in the arch direction, and the first rotating body 21 and the second rotating body 22 are integrally connected. Install the buried hinge connector (2) in the state of the form (19). When installing the buried hinge connector 2 in the formwork 19, a gap may be left between the adjacent buried hinge connectors 2, but the upper buried parts 212 and 222 and the lower buried parts 211 and 221 are In the case of a bar member, the plurality of buried hinge connectors 2 are formed in a line in a state in which they are integrated by inserting the bar members into each other or connecting the plurality of buried hinge connectors 2 to each other as illustrated in the drawing by other methods. (19) can be placed within.

The upper body 11 is manufactured by pouring concrete so that the lower buried parts 211 and 221 of the buried hinge connector 2 are buried. That is, as shown in FIG. 11 , concrete is poured into the formwork 19 so that the lower embedding parts 211 and 221 of each of the first rotating body 21 and the second rotating body 22 are embedded in the concrete. To manufacture the lower body 11 . At this time, the upper buried portions 212 and 222 of the first and second rotating bodies 21 and 22 respectively protrude above the lower body 11 . 12 is a schematic lateral side view of a state in which the lower body 11 is manufactured.

Subsequently, as shown in FIG. 13 , additional concrete is poured to a predetermined thickness so that the upper buried portions 212 and 222 of the buried hinge connector 22 are buried on the lower body 11 to form the upper body 12 . Although the lower body 11 and the upper body 12 are each formed by pouring concrete separately, the lower buried parts 212 and 222 and the upper buried parts 211 and 221 are integrally formed with the first rotating body. Since the 21 and the second rotating body 22 are embedded across the lower body 11 and the upper body 12 in each concrete block, the lower body 11 and the upper body 12 are integrally formed.

In the above description, it has been described that the entire concrete block 1 is manufactured by arranging the formwork 19 in a line and arranging the buried hinge connector 2 over the entire length of the arch direction of the block assembly 100 to be manufactured. Otherwise, the first concrete block 1-1 in which the first rotating body 21 is embedded and the second concrete block 1-2 in which the second rotating body 22 is embedded are separately manufactured. Then, the block assembly 100 of the present invention may be manufactured in such a way that the first rotation body 21 and the second rotation body 22 are rotatably connected to each other in the rotation coupling part 23 .

In addition, as illustrated in FIG. 7 , when the buried hinge connector has a separation/assembly configuration of the upper buried part and the lower buried part, when the lower body 11 is manufactured, the lower buried parts 211 and 221 of the buried hinge connector 2 are After filling the bay with concrete, after the production of the lower body 11 is completed, the upper buried parts 212 and 222 are assembled to the lower buried parts 211 and 221 to complete the buried hinge connector, and then the upper buried part 212 , 222) may be manufactured so that the upper body 12 is embedded in the concrete.

14 is a schematic perspective view showing that a plurality of concrete blocks 1 are bent in various shapes in a state in which they are integrally connected by an embedded hinge connector 2, and as shown in the drawings, the block of the present invention In the assembly 100 , the adjacent concrete blocks 1 may be rotated and bent in the vertical direction using the rotation coupling portions 213 and 223 of the buried hinge connector 2 as hinge points. When the block assembly 100 is completed, it is placed on the ground in the same state as in FIG. 1 . In order to construct a structure such as a bridge using the block assembly 100, the upper body 12 is raised using a lifting equipment such as a crane. The block assembly 100 is lifted in a state in the In the block assembly 100, adjacent concrete blocks 1 are connected to each other in a form that can be rotated and bent in the vertical direction at the point where they are connected, so that when the block assembly 100 is lifted, the buried hinge connector (2) The both sides of the concrete block 1 rotate with the rotational coupling part of the hinge point as a hinge point, and accordingly, the block assembly 100 conforms to the designed shape as shown in FIG. 2 as it is naturally bent at the hinge point between the concrete blocks 1 to form an arch structure having an arch shape. As such, during the formation of the arch structure, in the present invention, since a separate tension does not act on the lower body 12, a problem of the prior art, that is, when the block assembly is lifted and made into an arc shape, tension occurs in the reinforcing bar or steel wire. As a result, it is possible to prevent the occurrence of local damage to the concrete block and the phenomenon that both ends of the arch structure are indented. In forming the upper body 12, if necessary, for the concrete block 1 at a predetermined position, as shown in FIG. 14, the anchor bolt fixing part 121 may be formed in advance. The anchor bolt fixing part 121 may be formed as a concave groove. The utilization of the anchor bolt fixing part 121 will be described later.

On the other hand, in the present invention, the end concrete block positioned at each of both ends of the arch direction of the block assembly 100 may be integrally provided with a guide cone member 4 as necessary. 15 is a schematic perspective view of the circle B part of FIG. 1 showing the installation configuration of the guide cone member 4, and FIG. 16 is a schematic lateral side view of the part shown in FIG. . In the case of an end concrete block located at both ends of the block assembly 100 in the arch direction, an expansion flange part 120 extending in a vertical direction is further formed on the upper body 12, and the expansion flange part 120 has The guide cone member 4 may be integrally provided in a shape protruding toward the end in the arcuate direction. The guide cone member 4 may be formed of a conical member that becomes sharper toward the end in the arcuate direction. The guide cone member 4 may be provided in plurality.

When the guide cone member 4 is provided in this way, as shown in FIG. 16 , as shown in FIG. 16 , the arch side surface of the end concrete block becomes the arch side surface of the adjacent concrete block while the weight of the guide cone member 4 acts in the vertical direction. Naturally close to the block assembly 100 is a great help in achieving the designed arc shape. That is, a vertical load is applied to the end concrete block in the vertical direction as shown in FIG. 16 by the weight of the guide cone member 4 provided in the end concrete block. The moment force due to the weight in the expressed form acts. This moment force causes the end concrete block to adhere well to the adjacent concrete block in the arch direction without being lifted up. Therefore, the block assembly 100 naturally forms an arch shape conforming to the design without lifting both ends in the arch direction, and when installing the arch structure having an arch shape on the base part 5, both ends of the arch structure The advantage of being able to improve the efficiency of the installation work is exhibited by eliminating the need for a wire pulling operation to pull it toward the center of the arch.

Hereinafter, a process of constructing an arch structure such as a tunnel or a bridge by making the block assembly 100 of the present invention into an arch-shaped arch structure and arranging a plurality of them consecutively in the lateral direction will be described.

17 is a schematic perspective view showing a state of constructing an arch structure by lifting the block assembly 100 of the present invention and installing it between the base parts 5, and in FIGS. 18 and 19, respectively, the circle of FIG. A schematic lateral side view of part D is shown. 18 shows a state before the guide cone member 4 is inserted into the guide hole 50 , and FIG. 19 shows a state after the guide cone member 4 is inserted into the guide hole 50 . In the present invention, after the block assembly 100 having the above configuration is pre-fabricated at the factory, transported to the site and lifted by a crane to make an arch shape, between the base parts 5 installed at intervals in the lateral direction will be held on At this time, the end concrete blocks located at both ends in the arch direction of the block assembly 100 are placed on the base part 5. When the guide cone member 4 is provided in the end concrete block, the end concrete blocks are in contact. A guide hole 50 into which the guide cone member 4 is inserted is concavely formed on the upper surface of the base 5 . In this configuration, when the block assembly 100 in an arcuate state is mounted on the base 5 , the guide cone member 4 is inserted into the guide hole 50 and fixed. After the guide cone member 4 is inserted into the guide hole 50 , if necessary, the guide hole 50 is filled with a filling material such as mortar so that the guide cone member 4 is inserted into the guide hole 50 . fasten firmly.

The coupling configuration of the guide cone member 4 and the guide hole 50 exhibits the advantage of allowing the block assembly 100 to be mounted on the base part 5 at a predetermined position more easily. When the size of the guide hole 50 is sufficiently large, the guide cone member 4 is easily inserted into the guide hole 50 even if an error occurs during manufacturing or construction, and the block assembly 100 is positioned at the base ( 5) is mounted on In this way, when the block assembly 100 is mounted on the base 5, the guide cone member 4 is firmly fixed in a state inserted into the guide hole 50, so that during the mounting process of the block assembly 100, conduction, etc. can effectively prevent accidents from occurring. In particular, since the upper surface of the base part 5 in contact with the end concrete blocks 1-3 as shown in the drawings is made of an inclined surface, when the block assembly 100 is mounted on the base part 5, the guide cone The member 4 is easily inserted into the guide hole 50 in an oblique direction. When the diameter of the guide hole 50 and the diameter of the guide cone member 4 are made the same, the block assembly 100 is placed in an accurate position while the guide cone member 4 is fitted and fixed in the guide hole 50 . However, if the size of the guide hole 50 is sufficiently large as mentioned above, the block assembly 100 is not placed in the correct position immediately after the guide cone member 4 is inserted into the guide hole 50, but manufacturing or construction Even if a time error occurs, the guide cone member 4 can be easily inserted into the guide hole 50 , and after the guide cone member 4 is inserted into the guide hole 50 , the position of the block assembly 100 . After adjustment, by filling the guide hole 50 with a filler such as mortar and fixing the guide cone member 4 in the inserted state in the guide hole 50 , the block assembly 100 can be firmly installed.

As illustrated in FIG. 17 , the block assembly 100 is lifted into an arch shape and installed between the base parts 5 at both ends in the arch direction, and a plurality of block assemblies 100 are sequentially arranged in the transverse direction, such as tunnels, bridges, etc. Build an arch structure.
